Control Timer Values (sec)
The following table describes all control timer parameters. Each value is displayed
in seconds.
Field Description
Reorder Delay Delay after far end hangs up before reorder tone is played. 0 =
plays immediately, inf = never plays. Range: 0–255 seconds.
Defaults to 5.
Call Back Expires Expiration time in seconds of a call back activation. Range: 0–
65535 seconds.
Defaults to 1800.
Call Back Retry
Intvl
Call back retry interval in seconds. Range: 0–255 seconds.
Defaults to 30.
Call Back Delay Delay after receiving the first SIP 18x response before declaring
the remote end is ringing. If a busy response is received during
this time, the Cisco IP phone still considers the call as failed and
keeps on retrying.
Defaults to 0.5.
Interdigit Long
Timer
Long timeout between entering digits when dialing. The interdigit
timer values are used as defaults when dialing. The
Interdigit
Long Timer
is used after any one digit, if all valid matching
sequences in the dial plan are incomplete as dialed. Range: 0–64
seconds.
Setting this value high can result in a longer post dialing delay
(PDD), which is the time between the start of a call and the time
the phone starts ringing. A value that is too low can result in dialed
digits not being correctly recognized.
Defaults to 10.
